Usability, particularly ease-of-use, is a main factor affecting the acceptance of technologies by older adults. Mobile devices offer great possibilities for well-being applications, but they are often equipped with touchscreen. In order to evaluate the ease-of-use of tactile interaction, this study compares the performances of 16 novice (mean age 74) and 8 experienced older adults (mean 75) during the execution of drag-and-drop interaction for achieving tactile puzzle games on smartphone and tablet, with pen and fingers. Results show that novice users were able accomplish interaction accurately with longer times but no significant difference of errors of accuracy.
